A high-order, conservative and positivity-preserving intersection-based remapping method between meshes with isoparametric curvilinear cells
Nuo Lei, Juan Cheng, Chi-Wang Shu
This paper presents a novel intersection-based remapping method for isoparametric curvilinear meshes within the indirect arbitrary Lagrangian-Eulerian (ALE) framework, addressing t…

A structure-preserving multiscale solver for particle-wave interaction in non-uniform magnetized plasmas
Kun Huang, Irene M. Gamba, Chi-Wang Shu
Particle-wave interaction is of fundamental interest in plasma physics, especially in the study of runaway electrons in magnetic confinement fusion. Analogous to the concept of pho…
